I wouldn't put a lot on money in a car that I wouldn't be happy with for a long, long time. My 02 ZL1 will not be worth anywhere near what I will have in it until I am long gone. If ever. But, I love the late model SS body style and need to see one everyday. I guess that's why I have a black, 1LE SS on a lift in my garage. I like to drive it but even if I didn't I would still have to have it.
The supercharged C5R 427 ZL1 will be virtually useless on the street but I still want it. It's kind of like looking under the hood of a hemi. If someone has to ask why you are glass eyed, mesmerized and drooling after an hour or so don't even bother trying to explain it to them.
